The invention is whic'lilthefollowing d's'ciiri: tion relates is a novel recei er for power operated nut removing tools.

In removing nuts fromlboltsgby backin tliein oil or unscrewing them. use is generally. made .of an electric or air driven. socket wren h. .,These tools operate at considerable speed and tneop; eration is slowed by the requirementof.collecting the nuts or removing them individually from the sockets. Where the tool has a hollow head through which the loose nuts are fed and ultimately discharged, the nuts are scattered over a considerable area and frequently lost or otherwise become a nuisance. It is an object of my invention, therefore to provide means adapted for mounting on a rotary nut removing tool by which the nuts may be collectedas they. aresum cessively removed and conveyedaway from the socket Wrench. l. A. further obectofmy invention is to prevent such nuts from flying-centrifugally from the hollow shaft of a power driven tool and thus becoming lost or otherwise being a source of nuisance and inconvenience.

A still further object of my invention is to provide an accessory in the form of a holder for the removed nuts suitable for use with tools of existing designs.

Among the objects of my invention also is to provide an accessory for the purpose intended, and which permits periodic discharge of the accumulated removed nuts.

Incidentally my invention is simple, easy and economical to manufacture, convenient to use and rugged and serviceable.

As illustrating one form of my invention I have shown the preferred form on the accompanying drawings by way of example in which:

Figure 1 is a side elevation in outline of a. rotary socket wrench equipped with my nut receiving holder or magazine, and

Fig.2 is a vertical longitudinal section of the receiver and associated wrench shown upon an enlarged scale.

I have illustrated my invention as applied to a conventional and well-known type of power driven rotary tool assembly 3. This tool may be operated by electrical, manual, pneumatic or mechanical means to rotate its shaft and the shank or shaft 4 connected thereto.

The nut removing tool proper consists of a. steel shank or shaft 4 fastened to one end of the power driven shaft of the rotary tool 3.

The shaft 4 has an end 5 reduced in diameter and provided with a shoulder 6. A central passageway 1 runs longitudinally of thes ha'ft 4.in'; wardly mthe nd oppo t ts a achm n i the shaft of tool assembly 3. Intermediate the length of the shaft 4 there is alateral ejector outlet 8 which extends through the sidewall of the ha t 5 a d co nects. withiias' aeewav ii. l The free end of the reduced part ioithe shaft carries a suitable socket wrenchill adapted'to iii; the particular type and size rnuts being removed. This adapter also a central; passageway in o ect n With pa a ewa T e soc et wrench 19; is iirmlyfast' ned in they s ame and preferably may be removably connected t'h f Thepassageways 1 and it; are of materially greater diameter than-the opening i t Qthe socke rench 9' so that loosened nuts pushed into passageway .IO from" the wrench 9 will travel freely toward theoutlet 8'; g L i v I- have provided a recei zer or ma'gaZine" J I to receive the nuts discha gedce'ntri'fugally orian ing by gravity from the outlet 8. This receiver may be of any suitable shape and size. Preferably it may hold from 250 to 300 loose nuts and may be of cylindrical form as shown.

The upper side walls of the receiver II have a pair of aligned round openings I 2, l2. Surrounding each opening I 2 are provided on opposite sides flange bearing members I3, l4 which may be welded or otherwise secured to the side walls.

The outer flange bearing member 13 abuts loosely against the integral shoulder 6 of the shaft 4. On the opposite side of the receiver H and slightly beyond the outer bearing l4, the hollow shaft 5 is grooved as at l5 to receive a resilient split ring retaining collar it. The magazine is therefore mounted on the shaft 4 and its extension 5 to permit the shaft to rotate freely within the openings l2.

The receiver II is open at the bottom and carries on one side a hinge H. A bottom plate or cover [8 is attached to the hinge l7 and extends across the opening of the receiver 1 i. On the opposite side a bottom [8 carries a spring latch in removable engagement with a detent 20 on the outer surface of the wall of the receiver to permit convenient removal of nuts collected within the magazine.

The rotary shaft and wrench form part of the usual power driven tool. A receiver of the above description may be slipped over the reduced part of the hollow shaftB and retained loosely thereon between the shoulder 6 and the split ring IS. The bearings l3 and I4 provide for a support of the magazine on the shaft. Thus the shaft 5 may be rotated at relatively high speed while the re- 1 opposite outlet 8. At

3 ceiver remains suspended on its bearings with its center of gravity below the shaft.

As the nuts are successively backed off from their bolts they will feed backwardly and loosely through the passageways ill and 1 until they are this point they fall by gravity into thereceiver as indicated in Fig. 1. If the shaft is rotatingvery fast and the nuts are discharged with any centrifugal force, the re ceiver serves to confine them against scattering of loss.

The operation of removing the nuts may be carried out rapidly and easily until the receiver contains a considerable number. 7 matter of a moment only to release spring latch l9 and to permit the bottom H! to drop, discharghollow endof the shaft, said shaft having an outlet between the shoulder and groove, a receiver journaled on the shaft between the shoulder and groove, a removable retainer ring mounted inthe groove, a, removable bottom elo- It is then a r ing loose nuts in any storage bin or other selected spotfor again using them.

While I have illustrated and described my preferred form of the invention, it may be given several embodiments with minorchanges in shape and proportions; Consequently the invention is to be limited only by the scope of the appended claims. V

WhatIclaim is: V r

1. In combination, a nut-removing tool comprising a rotary hollow shaft having a nut-holding socket at one end, a shoulder on the shaft, said shaft having an outlet between the shoulder and the nut-holding socket, a receiver having alined openings in its opposite sides above its normal center of gravity, journal bearings surrounding said openings, and removable means for holdingthe receiver loosely on the shaft adjacent the shoulder and over the said shaft outlet.

2. In combination, a nut-removingtool comprising a rotary hollow" shaftflhaving a'nut-receiving socket at one end, a shoulder on the shaft, said shaft having an outlet between the shoulder and the nut-receiving socket alined openings inits opposite sides'above its a receiver having 7 'low shaft journaled in sure hinged to the receiver, and means for latch ing the bottom in closed position.

4. A nut-removing tool comprising a box-like receiver having a removable closure, and a holopposite side walls of said receiver intermediate the top and bottom walls of the latter so as to be freely rotatable in relation to, the receiver and to protrude therefrom with both its ends, one of said ends embodying means to apply a rotative force to said shaft, the other end-being shaped to engage a nut circumferentially,

provide a permanently unobstructed passage for aihut from said other end throughsaid shaft intosaid receiver. j f BERT PABIZO.
